Eyes.

My fault should have anticipated this. The reason why Machos eye's arn't working in the render is because they've got nothing to react too. Macho isn't lit from the front at all other than 1 fill light and the sun lights.

I can forsee two ways of fixing this, unfortunalty both involve light linking...which i'll be honest i cant make heads nor tales of and can't find a tutorial explaining how to get it to work.

1: ON the eye spheres remove all influence of all lights in the scene, Maya then creates a "ghost" default light behind the camera which the reflection should react too...this ideas a bit shaky but should work but failing that -
2:Create a spotlight behind the camera that effects the eye spheres and only the eye spheres.
